CustomFileModel.cpp

/*
 * This Class is a reimplementation of QFileSystemModel.
 * The default class provides all required functionality by default, and as such,
 * handles drop events internally.
 *
 * Files draged from the server technically do not exist on the local system
 * The default model does not know how to handle the custom mime type
 * It does not need to try and move/copy the files
 * It just needs to send the data to the downloader class to add to the queue.
